Thanks for your help so far. I think I may have found the cause of the issue. There was a bug in the hash table routine, introduced in v7.46, that would have resulted in incorrect freeing of memory in some contexts. I was not able to reproduce a crash but this particular issue would have caused a crash eventually/intermittently. Hopefully it is the same bug that is causing your issue. I have uploaded a new beta here.

Got it installed, will report back when it's survived hours of activity or when it crashes, whichever happens to be the case.

Okay, a streamer did a morning stream that lasted over 5hrs with no issues. Not saying that it means the issue is solved, but it's a good sign.

mIRC uptime is over 19hrs at this point. Will wait until another couple of streamers have been on for a few hours (should be starting in a few hours from now). I have a good feeling about this, but again, not jumping the gun.
